73-350 swap

Hey. I've got what you're looking for. I replaced the 260 in my 80 Cutlass, with a freshly rebuilt 350, which I originally built for my 73. (73 got a 455 instead.) Here's the basics, specs are in a filing cabinet. 73 block, bored 0.30 over, stock bottem end. 71 heads,(bigger exhaust valves), 80 delta 88 350 intake, not ported... yet.. (for egr valve), mild cam. No change in rise, just valve duration, no mods to heads for that, rochester 4bbl from same intake, rebuilt, stock primaries, secondaries changed to 69 w25 specs/rods.(I think) It's up against a th400 tranny, rebuilt with a shift kit. The best upgrade was a bual snorkel breather, which I made myself. (see attach) The car will break loose going into second now. Main upgrade!!! Air intake, and car passed it's last required e-test, without the air pump. (Ontario, mind you.) PM me if you want more specs. Good luck. Jim.
